The Royal Indian Navy (RIN) was the naval force of British India and the Dominion of India. Along with the Presidency armies, later the Indian Army, and from 1932 the Royal Indian Air Force, it was one of the Armed Forces of British India.
Maritime powers in the Indian subcontinent have possessed navies for many centuries. Indian dynasties such as the Chola Empire used naval power to extend their influence overseas, particularly to Southeast Asia. The Marakkar Navy under Zamorins during 15th century and the Maratha Navy of the Maratha Empire during the 19th and 18th centuries fought with rival Indian powers and European trading companies. The East India Company organised its own private navy, which came to be known as the Bombay Marine. With the establishment of the British Raj after the Indian Rebellion of 1857, the small navy was transformed into "His Majesty's Indian Navy", then "Her Majesty's Indian Marine", and finally the "Royal Indian Marine".
The Arabis class was the third, and largest, of the five sub-classes of minesweeping sloops completed under the Emergency War Programme for the Royal Navy in World War I.

The ships were also used outside their minesweeping duties as patrol vessels, tugs, and personnel and cargo transports.

CS Alert, or HMTS Alert, was a cable-laying ship that had a significant role in World War I. She was launched in 1871 for the Submarine Telegraph Company with the name The Lady Carmichael. In 1890 the ship was acquired by the General Post Office (GPO) as part of the nationalisation of the British telegraph network. At the outbreak of World War I, Alert was immediately dispatched to cut German telegraph cables in the English Channel, seriously damaging Germany's ability to securely communicate with the rest of the world. Alert was taken out of service as a cable ship in 1915 but her cable-handling gear was retained for fitting on her replacement.
